Title: Pattern forming method
Inventor: OGAWA TARO
IPC: G03F7/40
Filed: 1996-05-10
Abstract: PROBLEM TO BE SOLVED: To prevent inclination of a micro resist pattern after development, reduce consumption of a developing solution and prevent nonuniformity in development by exposing an exposed resist film to vapor of a solvent to polymerize solvent molecules on the exposed part, and evacuating vapor to evaporate the resist film and a polymerized matter of a solvent, thereby performing development and forming a resist pattern. SOLUTION: An exposed resist film 2 is exposed in an atmosphere of vapor 5 and held therein for a fixed time. Whereupon, vapor molecules 6 cause radical polymerization and ion polymerization to be polymerized with radical or ion produced in the resist polymer of the exposure part. At this time, if the polymerized matter 7 is volatile, the polymerized matter 7 is evaporated by evacuating the vapor 5, and a positive type resist pattern 8 is formed. According to this method, a solvent is introduced by vapor with saturated vapor pressure, so that the consumption is several ml, which is reduced to one-tenth or less of the wet development, and vapor is diffused to the whole surface of a wafer so as to reduce nonuniformity in developing solution.

IPC: H05K1/02
Filed: 1984-06-07
Abstract: PURPOSE:To stabilize a resonance frequency of a dielectric coaxial resonator by connecting electrically an inner peripheral electrode, an outer peripheral electrode of the dielectric coaxial resonator and lands of a printed board by means of soldering. CONSTITUTION:The outer peripheral electrode 17 of the dielectric coaxial resonator 11 is soldered to the earth lands 14 of the printed circuit board 16 by solder 15. Further, the lands 13 of the printed circuit boards 16 and the inner peripheral electrode 12 of the resonator 11 are soldered by the solder 15. Since no center conductor is required in this way, the distortion due to thermal expansion is reduced. Since the board 16 is not a solid body, a force of the inner peripheral electrode 12 of the resonator 11 is decreased, thereby causing the resonance frequency of the resonator 11 to be unchanged. A conductive adhesives is used in place of soldering. Thus, the resonance frequency of the dielectric coaxial resonator is stabilized.

Abstract: PURPOSE:To reduce the series resistance values of a solar battery by forming a finger section in a vacuum evaporation process and a bus bar section in a printing process when forming the electrodes made of the finger section and the bus bar section on the surface of the battery.
